IEEE802.11b/g/n Wireless LAN USB 2.0 Client Adapter Version 1.0 7 1.5 Applications The wireless LAN products are easy to install and highly efficient. The following list describes some of the many applications made possible through the power and flexibility of wireless LANs: a) Difficult-to-wire environments There are many situations where wires cannot be laid easily. Historic buildings, older buildings, open areas and across busy streets make the installation of LANs either impossible or very expensive. b) Temporary workgroups Consider situations in parks, athletic arenas, exhibition centers, disaster-recovery, temporary offices and construction sites where one wants a temporary WLAN established and removed. c) The ability to access real-time information Doctors/nurses, point-of-sale employees, and warehouse workers can access real-time information while dealing with patients, serving customers and processing information. d) Frequently changed environments Show rooms, meeting rooms, retail stores, and manufacturing sites where frequently rearrange the workplace. e) Small Office and Home Office (SOHO) networks SOHO users need a cost-effective, easy and quick installation of a small network. f) Wireless extensions to Ethernet networks Network managers in dynamic environments can minimize the overhead caused by moves, extensions to networks, and other changes with wireless LANs. g) Wired LAN backup Network managers implement wireless LANs to provide backup for mission-critical applications running on wired networks. h) Training/Educational facilities Training sites at corporations and students at universities use wireless connectivity to ease access to information, information exchanges, and learning. 1.6 Network Configuration To better understand how the wireless LAN products work together to create a wireless network, it might be helpful to depict a few of the possible wireless LAN PC card network configurations. The wireless LAN products can be configured as: a) Ad-hoc (or peer-to-peer) for departmental or SOHO LANs. b) Infrastructure for enterprise LANs. a) Ad-hoc (peer-to-peer) Mode This is the simplest network configuration with several computers equipped with the PC Cards that form a wireless network whenever they
IEEE802.11b/g/n Wireless LAN USB 2.0 Client Adapter Version 1.0 8 are within range of one another. In ad-hoc mode, each client is peer-to-peer, would only have access to the resources of the other client and does not require an access point. This is the easiest and least expensive way for the SOHO to set up a wireless network. The image below depicts a network in ad-hoc mode. b) Infrastructure Mode The infrastructure mode requires the use of an Access Point (AP). In this mode, all wireless communication between two computers has to be via the AP. It doesn’t matter if the AP is stand-alone or wired to an Ethernet network. If used in stand-alone, the AP can extend the range of independent wireless LANs by acting as a repeater, which effectively doubles the distance between wireless stations. The image below depicts a network in infrastructure mode.

LEAP is one of several protocols used with the IEEE 802.1X standard for LAN port access control. LEAP also delivers a session key to the authenticated station, so that future frames can be encrypted with a key that is different than keys used by others sessions. Dynamic key delivery eliminates one big vulnerability; static encryption keys that are shared by all stations in the WLAN.
